How to send output message data of electronic switching system

Since this is an open matter, no full text was included.

1 is a structural diagram of an electronic switching system to which the present invention is applied, FIG. 2 is a flowchart of a method of transmitting output message data according to the present invention, and FIG. 3 is a flowchart of an initialization routine for transmitting output data of FIG.

Claims (6)

ASS (Access Switching Subsystem) (1) which performs call processing function and its own operation and maintenance function, overall maintenance and operation management function of system, test and measurement, statistics, control management of auxiliary memory device, operator and CCS (Central Control Subsystem) (3) that performs matching function with other systems, and performs number translation, route control function, and concentration function, and has a network synchronizer to generate and distribute a system clock and to generate the system clock. A method of transmitting output message data of an electronic switching system comprising an INS (Interconnection Network Subsystem) 2 which connects to each other or between an ASS 1 and an CSS 3 in an optical link; When output data is generated, a first step 201 to 204 of allocating a transmission area for transmitting output data, a second step 205 and 206 of transmitting the output data, and a third step of terminating the output data transmission ( 207), characterized in that the output message data transmission method. 2. The method of claim 1, wherein the first step comprises: a first step 301 of searching for a transmission area that can be allocated; a second step 303 of prohibiting reassignment of an allocated transmission area if there is a transmission area; And a third step (304) of setting a field value of the transmission area. The method as claimed in claim 1, wherein the second step comprises a first step (401, 402) of setting a variable variable when the output data is variable data, a second step (403 to 408) of searching for and processing characteristics of the output data, And a third process (410 to 412) of writing the output data to the transmission memory area. The method of claim 1, wherein the third step includes a first process 501 of adding a transmission termination control character to the transmission area, a second process 502 of transmitting the output data, and reassignment of the allocated transmission area. Output message data transmission method, characterized in that performed by a third process (503) to allow. The method of claim 3, wherein the second process comprises: a first process of recognizing the type of the output data and recognizing that the characteristic of the data is a 4-byte integer, 2-byte integer, 1-byte integer, character, string, string constant, etc .; And a second process of recording the output data in a temporary memory area according to data characteristics. 4. The method of claim 3, wherein the third process comprises: a first process 410 of retrieving a size of a transfer memory area; a second process 412 of writing the processed output data to a transfer memory area if a transfer memory area exists; And a third process (411, 412) of recording the processed output data from the beginning of the transmission memory area after transmitting already recorded data if the transmission memory area is insufficient. ※ Note: The disclosure is based on the initial application.
